Fig. 2 as long as the door isopen. If the door be forced shut the knob 25. will still be free to pass around the surface 31 on the kee er plate and snap back into its socket 28 ut the horizontal plunger 13 will be forced to the rear by the surface 15 traveling over the surface 29 of the keeper and as the device reaches the position shown in Figs. 1 and 3 this movement of 13 will be such as to bring the notch 30 fully opposite the vertical plunger 18 and this plunger will be raised by the spring 23 to bring thefinger 21 to position against the stop 27.

When in this position the parts are securely locked.-

,While we have described our device in considerable detail it will be obvious that many changes in these details and arrange,

ment of parts may be made without depart: ing from our invention and we do not, there-v fore, desire-to be considered as limited to i the recise form shown and described. aving thus described our invention what we'claim and desire to secure byLetters Patent is:

1. In a device of. the class described, a

latch and keeper, said latch comprising a member resiliently .projectedtherefrom', an: oscillating finger in position to engage said member in normal position of the device to lock the member in projected position, a"

pilunger connected to said finger to move the nger from the path of said member, a

spring tending to resistsuch action, and spring pressed means adapted to engage said plunger to retain said finger in :1no

erative position. I

2. In a device of the class described, a

latch and keeper, said latchcomprising a member resiliently projected therefrom, an

oscillating finger in position to engage said 7 member in normal positioniof the device to lock the member in projected position, a plunger connected to said finger to movethe nger from the ,path of :said member, a. spring tending to resist such action, and a catch adapted to engage said plungertorc tain said finger in inoperative position while the latch is away fromthe keeper.

3. In a device of the class described, a latch and keeper, said latch comprising a member resiliently projected therefrom, an oscillating finger in position to engage said member in normal position of the device to lock the member 1n projected position, a

plunger connected to saidfinger to move the nger from the path of said member, a

spring tending to resist such action, and a the rear of said knob in normal position of the device, a plunger connected to said finger to depress-the same, a spring tending to resist such action, and a catch adapted to engage saidplunger to retain said finger inxinoperative position while the latch is away from the keeper.

5. In a device of the class described, a latch and keeper, said" latch comprising a spring; ressedkno'b projecting therefrom,-.

an oscil atingifinger, in position to engage the rear'of said knob in normal position of thedevice, aplunger connected to said fin- ,ger to depress the-same, a spring. tending to resist such action, and a spring pressed catch adapted to engage a -P to retain the same in depressed position, said keeper comprisingarec'ess adapted to re- --ceive said knob and an inclined surface adapted" to repress said catch to free said plunger.

6. Ina device of the class described, a

latch and-keeper, said latch 'comprising a spring, a stop on said" spring in the path of/s'aid finger, a plunger- 'co'nnectedto' said finger to depress the same, asprin'g tending to resist such actionysaid plunger having a notch thereim'a spring pressed catch adaptand by engaging the same to hold said plunglersin depressed position; said catch also saidplungerto travel when said catch is repressed, said keeper comprising a recess adapted to receive said knob and an inclined faceadaptedto repress said catch,

In'testimony whereof we have hereunt afiiik'ed our-signatures. Y
